My invention is capable of embodiment .in many different forms, andWhile l shall illustrate it by an embodiment Which may be considered animprovement upon the coffee percolator shown in my Patent #1,005,096,

dated (lctober 3 19H, my invention is not to be coniined to theillustrated torni.

The illustrated torni ot my invention consists primarily of a percolatorproper and a pot which is adapted to contain and conceal thepei-eclater. The percolator comprises an outer vJanie l consisting ofaring E2 having a handle 3, the latter being ypreterably formed olfchina to con 'torin with the pot to be later described. Loops l and 5depend from the ring and torni in effect a basket to hold a iilterclothv 6, which may be a plain piece ot cloth and does not require anycut-y ting 'or sewing into bag `forni. Fingers 7 are 'formed on orattached to one or more verticalpoii'tions ot the said loops,7 Whichfingers rest upon and are supported by a ledge Fig. 6 is a 1919. SerialNo. 304,430.

y8 that is termed on the body of the pot. i The lingers not only supportthe coffee percolator `proper but they space the percolator away rromthe side ot the` pot. This avoids con-` tact of the ilter cloth with thesides et the pot and consequently ot' leakage or dripping ot the Waterat points Where it is not desired.

rlhel filter clothis heldin bag torni Within the outer traine l by aninner trarne 9 consisting olf a ring l0 having Wires l1 dependingtherefrom and preferably secured together at the center. yThe Wires ilrise upwardly as they approach the center and are` so proportioned tothe loops of the outer tramethat the` lovveranost portions oi the bendsoi the Wires ll are at a 10W enough level to press the portion of theiilter ycloth which touchesthosebends below the level oi the portion oithe lter cloth which rests upon the crossed loops ot the outer trame.Thus, a plurality of separat-e depressions is made in the bottom or" thefilter bag, and the Water passing' through the ground coffee Will drip:troni the points thus formed and will be effectively distributedthroughout the inass olf coffee, so that the danger is lessened that anyolf the coffee will not be'properly percolutefl. Thisarrangement alsoaccomplishes the percolationmore speedily than would befthe case if thebag had only one point from which the. Water dripped and thus the timeoit contact ot the Water with the ground coffee is shortened. Thisenables the percolation to be accomplished with less danger of leaching'out the deleterious substances in the coilee bean and insures that thecoiiiee will only contain the desired elements ol the coffee which arethose that will most quickly dissolve iu Water. Ahis increased speed otpercolation also reduces the time of contact oit' the collec With themetal ot the Wires,- which is a desirable thing to accoinplisln` aharmful ychemical action tends to set up between the coffee and theinetal. l

My i'orin oit percolator.enables a relatively large amount o'tcotfeegrounds to be contained in a comparatively small pot Without causing thecoffee grounds to be percolated ico the two frames together with thelilter cloth between them.

The parts are preferably so proportioned that the bottom ot' the iiltercloth cannot be come submerged in the water in the body of' the pot;that is, the exit of the spout isnat a level below the bottom oitthelilter cloth. Thus, the colee grounds in the filter cloth cannotsteep in the made coffee standing in the bottom of the pot.

l vdesire to so construct the pot that the coffee percolator proper, asbei'ore stated, 'will be concealed and yet to maire the parts of chinaso as to avoid as much as possible the harmful etlect from the coll'eecoming in contact with metal. lt is desirable for thisreason to make thebody of the pot ol china. It is also desirable' for the sake ofappearances to make the parts enclosing the percolator proper oft china.l have theretore provided a percolator enclosurev lin the `form of aring l2 having` an opening throughr which the handle 3 may extend, suchopening being preferably in the form ot ahole lll, as the hole does notweaken the ring1 to any great extent. This construction maires it salteto form the casing oi pottery, as would not be so desirable to do itonly a notch were provided for the handle. At the upper edge of the ring125` -just above the' level of the `iframes holding` the filter cloth, atunnel l5 is formed which is preferably integral Vwith the ring. rlhelower edge ott the funnel preferably comes just below the level of therings at the top oft the trames oit the percolator proper and thusserves as a gauge to indicate the level above which the' water shouldnot be permitted to rise` to prevent its overflowing the said frames andpassing down into the'body of the pot without going through the coffeeand also to prevent the overflowing water trom carry-` ing colleegrounds down into the bodyjof the pot. rlhe casing and percolator propercan both be raised from the pot by simply taking hold oat the handle 3,andthus the contents ot the pot can very easily be inspected at any timeto determine just how much coffee the pot encloses. The casing notonlyencloses and conceals the cloth and its unavoidable discolorationbut at the same time tends to hold in the heat during and a'lfter thepercolation. The casing, to

, a large extent, conceals the cloth even when the casing and percolatorproper are lifted oil3 to inspect the interior of the pot. rlhe onehandle thus serves both for the coffee percolator proper and the casing.The casing in passing down outside the percolator proper carries theedges of they lilter cloth downward out of the way of the water and outof sight. n

By changing the form or size of the inner frame .of the percolatorproper, `consisting of the ring l0 and theV wires attached thereto, thecapacity may be varied to suit the requirements as tothe amount orcollec to be made.

ll a-lsopreferably provide a lid 16 and form depressions both in the topof the coftee pot and in thetop of the cover to receive the lid, so thatthe latter can be used either on the cover or when the latter and theercolator proper yare removed, so that the lid can be yused on the bodyoit the coffee pot.

My percolator not only possesses the advantages heretofore mentioned butit may be said in general thatit enables coffee to be made which isotgreat purity, and to be made quickly and easily and with aneconoinicaluse of coffee grounds. While it also enables `a lter cloth tobe used which is merely a disc of cloth withoutany rnahing and which canbe removed and renewed with great facility, the cloth is entirelyconcealed inv a shapely pot. TWhile my pot enables coffee to be made bypercolation, the

`vertical dimension of the casing, in which the percolating parts arecontained, is coniparatively short` producing more attractive appearancethan a pot in which the said part is: taller. The casing which enclosesthe percolator proper serves to hold the percolator above the level ofthe coffee solution in the pot` which is a verydesirable object, as theimmersingA of the collecl grounds bythe rising of the collee solution,would res it in leaching out from the grounds the oils and otherprinciples which are deleterious and which l have take/naso much` painsto avoid. lt/loreover, when the cotlee solution has been termed, thecasing l2, and'with it the percolator, can be removed the pot, 4and thelid 16 placed upon the topv of the pot proper, thus both making thecollec pot (as shown in Fig-l) lighter and easier to handle and keepingthe coffee solution hot.
